MURDERED: Stephanie Casberg

00:00 / 00:00

AI Summary

This episode examines the unsolved 1969 murder of Stephanie Casberg, an 18-year-old waitress from Milwaukee whose dismembered remains were discovered along Wisconsin's Root River just one day before her birthday. The methodical dismemberment suggested someone with anatomical knowledge, while evidence scattered across multiple locations indicated the killer moved between Milwaukee and Racine County. Despite numerous leads over the decades—including suspicious coworkers, a mysterious man seen near the dump site, and various theories about motive—the case remains unsolved. Investigators have pursued multiple angles, from rumors about her father's disapproval of her interracial relationship to suspicious behavior by restaurant staff where she worked. Key persons of interest included restaurant manager R.S., who made odd comments about psychic predictions matching his initials, and cook Michael Bartelt, a Vietnam veteran who abruptly quit and left for Hawaii shortly after the murder. The case has recently gained renewed attention from Crime Junkie listeners, and detectives continue to follow new leads that emerge from the podcast's coverage.

"In several piles along the riverbank, half covered by mud and in a mix of torn brown paper bags and newspaper, were the dismembered remains of a teenage girl, or at least most of her. What police realized when they came to process the scene is this girl's torso and left leg were missing."

— Ashley Flowers

"The cuts at each joint are deliberate, methodical, like this is the work of someone who knew what they were doing."
